It is advised to use a linear PDF, this results in the best user experience.

A linear PDF is a PDF file that is (web) optimized. This increases the performances of the PDF when opened in browsers or PDF readers, such as Chrome, Safari, Edge, Firefox, Adobe Reader and so on.

A PDF/A variant is strongly recommended. By using PDF/A you ensure that the PDF will be displayed the same on all devices. You can read more about it on What is PDF/A?
